Means FOR LOOKING CAN-COVERS.

Specification of Letters Patent.

Patented July 1,1919.

Application filed March 24, 1919. Serial No. 284,579.

To all whomjt may concern Be it known that I, LINUS J. SCHILLIN- GER, acitizen of the United States, residing.

at Syracuse, in the county of Onondaga and State of New York, haveinvented certain new and useful Improvements in Means for LookingCan-Covers, of which the folowing is a specification.

This invention relates to means for look ing the covers of cans, and hasfor its object to provide a novel and simple locking device, designedparticularly for securing the covers of garbage and similar receptacles,for prevent-ing their accidental removal or loss.

I attain these objects by the means set forth in the detaileddescription which follows, and as illustrated by the accompanyingdrawing, in which- Figure 1 1s a top-plan view of a garbage or othercan, showing my improvement applied thereto.

' Fig. 2 is a side elevation of the same.

Fig. 3 is an enlarged broken vertical cross-section,substantially online 3-3 of Fig. 1; showing the pre erred construction and arrangementof the locking device; also showing by full and dotted lines theoperated and released positions of the lock.

Fig. 4 is an enlarged top view of the locking device in connection withfragments of the can and cover.

Fig. 5 is a horizontal section, taken on line 5-5 of Fig. 3.

Fig. 6 is an enlarged broken view of the latch, taken in the directionof the arrow steel 9, which is first bent like in Fig. 3.

Fig. 7 is a vertical cross-section, similar to Fig. 3; showing amodification of the locking parts, in leased positions. I

In the drawing, 2 represents a can, such as is used for depositinggarbage and other refuse. which is provided with the usual bead 2"around its-open top. 3 is the cover which telescopes the open top of thecan,

and 3" is the depending flange of the cover.

Both the can and cover may follow any of the usual constructions. Thediameter of the flange 3 is usually slightly greater than the outerdiameter ofthe beaded rim 2 of the can, as shown in Figs. 3 and 7 sothat the cover loosely fits the can.

My'i-mproved cover lock, in its preferred form, consists of a strip ofsheet spring an inverted both the operated and re-,

The body L having arms 9' and 9, both of which substantially conform tothe outer edge of the cover 3. The strip 9 is next bent upwardly at 9 toprovide a spring latch portion 9 the free end of which is again bentsubstantially at right angles to form a shoulder 9 which engages theunderside of the bead 2, the lateral portions of the shoulder being cutaway to provide a relatively narrow tongue 9 which passes looselythrough a slot 3 in the flange 3, and also through a corresponding slot9 in the arm 9. The free end of the tongue is provided with an enlargedhead 9 which is positioned outside of the ,arm 9. After the tongue 9 isinserted through the slot in the flange 3 and through the arm 9*, itsfree end is given a half-twist for positioning the head 9 in a verticalplane crosswise oi theslot 9". This prevents the tongue from becomingdetached from the part 9*, while permitting the latch 9 to be sprungtoward and away from the flange 3, when applying and removing the coverfrom the can. 10 is a narrow tongue-like spring which is struck ig. 3)sufliciently to allow the latch to pass finally restsby the bead 2'.lVhen the cover upon the top edge of the can, the latch and the tensionnormal positions, shown by the full lines in Fig. 3, which brings theshoulder 9 into locking engagement with the head 2. To remove the coverfrom the can, the operator grasps a. hand-knob 11", which is mounted ontoplof the arm 9, and forces thelatter outwardly, as from the full lineto the dotted line position frees the shoulder 9 from the head 2. Thecover may then be lifted clear of the can without interference from. thelock 9.

Fig. 7 shows certain modifications, which consists of a non-spring body11, similar in shape to the part 9, having arms 11' and 11*, the formersupporting a hand-knob 1 0. 11 is also bent at 11 to provlde art 10spring back to theirshown in Fig. 3, which an upwardly extending la-tchportion 11, the latter being bent toward the arm 11 to provide ashoulder 11 which engages the underside of the bead 2 of the can 2. Theshoulder portion 11 passes loosely through a slot 13 in the flange 3,and its free end bears against the inner face of the arm 11*. 14represents a bolt, which passes through alining perforations in the arm11*, the latch portion 11 and the flange 3, the said bolt eing held inplace by a nut 14:. 15 is a coil spring whlch encircles the bolt 14, itsopposite ends engaging respectively the latch 11 and the inner face offlange 3. The tension of the spring 15 normally holds the device in thelockin position, shown by the full lines in Fig. In applying, as well asremoving the cover 3- from the can, the locking parts are forcedoutwardly, from the full line to the .dotted line position (Fig. 7), asdescribed.

Having thus described my invention, what I claim is- 1. The combinationwith a can having an annular bead, and a cover having a depending flangeencircling said bead, of a locking device comprising an L-shaped body,one arm of said body'folded upon itself to provide a flexible latch,said latch having a shoulder engaging the bead of the can and having atongue which pierces the flange of the cover and said arm, the said bodyadapted to be tilted on said tongue for freeing said shoulder from saidbead.

2. The combination with a can having a beaded mouth and a telescopingcover having a depending flange, of a lock comprising an inverted L-haped body of spring material, one arm of said body bent upon itself toprovide a shouldered latch adapted to engage the bead of the can, saidlatch having a tongue which passes through slots in said flange and saidbody, and a spring carried by said latch and engaging the flange of thecover for normally holding said latch in the locking position.

3. The combination with a can having a bead around its mouth and a coverhaving a depending flange provided with a slot, of a lock supported bysaid flange, said lock comprising a spring metal body, a portion of saidbody bent U-shaped for receiving said flange, one arm of said U having ashoulder engaging the bead of the can for locking the cover to the can,and having a tongue adjacent said shoulder which passes through the slotin the flange and through the opposite arm of said U, and a spring forgorgially holding said shoulder beneath said In testimony whereof LINUSJ I aflix my signature.
